CONTROL-VALVE.

Specification of Letters Patent.

Patented Nov. 9, 1920.

Application filed May 7, 1919, Serial No. 295,410. Renewed August 27,1920. Serial- No. 406,524.

To all whom it may concern:

'Be it known that I, PETER MoJIco, a-

citizen of Russia, residing at I-lamtramck, county of .Vayne, and Stateof Mlchlgan,

, have invented certain new and useful Improvements in Control-Valves,of which the following is a specification.

This invention relates to improvements in devices for controlling theflow of water to a tankor the like, and has as its special object theprovision of a control valve in which a lever actuated plunger isoperated by a float in a novel and effective manner.

This object is attained by the novel construction and combination ofparts hereinafter described, and shown in the accompanying drawings,forming a material part of this disclosure, and in which- Figure 1 is aside elevationalview of a control valve made in accordance with theinvention, the valve being shown in an open position.

Fig. 2 is a similar view of the same, parts being in another position,showing the valve closed.

Fig. 3 is enlarged vertical sectional view taken through the controlvalves.

Fig. 4 is a side elevational view indicating the application of theinvention, and

Fig. 5 is a front view of the same.

Referring to the drawings, the numeral .1) indicates a tank adapted tobe filled with a fluid and having mounted thereon a casing 11, partlysupported by brackets 12, the

casing containing the mechanism for actuating the valve.

A platform 14 is formed with the valve body 15, the latter extendingcentrally downward, terminating in a flange 16 at its lower end, andcontaining a central, bored opening 18, extending through a screwthreaded stem 20 above the platform 14 and on which is engaged a packingnut 21, compressing a packing washer 22,

, against the stem 20. A plunger 24 is operable Within the opening 18,the plunger being normally pressed upward by a coiled compression spring25, the lower end of which abuts against a plate 26 secured to theflange 16 below this opening 18.

Extending laterally outward from opposite sides of the valve body 15 areelements 27 and 28, containing passages 30 which intersect the opening18 in the body of the valve.

Connected to one of the projections 28 is an inlet pipe 31 leading fromthe source of supply, while connected with the other projection 27 isanother pipe 32 leading into the tank 10.

Formed transversely through the plunger 24 is an opening 34 which may bebrought into registration with the passages '30, so that fluid may passdirectly therethrough or, when the plunger is in a lowered posi tion,the passages are closed.

Formed at the upper part of the stem 23 is a rectangular head 35containing a transverse recess 36, and in the bottom of the recess is adepression 37, the purpose of which will be farther on described.Elected upon the platform 14 is a standard 40, having a laterallyextending projection 41, bored to receive a spindle 42, provided with aknob or actuating head 43, the spindle passing downward through anappropriate opening in th platform 14, and'having engaged at its lowerend a float 44.

Upon the casing 11 is secured a sleeve 45, having a set screw 46,adapted to be manually operated whereby the spindle or rod 42 may belocked in any desired position.

Rigidly attached to the spindle 42, is an arm 48, carrying in its outerend a pin 49, engageable in a slot 50, formed in the inner end of alever 51, pivoted on a pin 52, set in the upper end of a standard 53secured on the platform 14. The opposite or outer end 54, of the lever51, is pivotally engaged with a link 55, the opposite end of which ispivotally engaged with another lever 56, pivoted on the pin 57, set inthe standard 40. The lever 56 passes through a slot 59 in the standard53 and the transverse recess 36, of the plunger head and is formed withan angular lug 58, engageable with the in dentation 37 formed in therecess so as to V operatev therein.

Formed with the lever 56, is an angular lug 60 adapted to .make contactwith the extreme upper end of the slot 59, in the standard 53, therebylimiting the upward movement of the plunger, a similar lug 62 beingformed on the lower side of the lever arm 54 adapted to make directcontact with the inner side of the standard near its top.

In operation, the parts having been assembled in the manner indicated,and the tank in an empty condition, obviously the float 44 extendingtherewithin, due to its weight and attached parts, increased by theoperation of the spring 25, causes the float to assume its lowermostposition, as indieated in Fig. 1, at which time the stop 62 will be incontact with the upright 53.

When the liquid has risen inthe tank so as to elevate the fioat 44,moving the spindle l2 so as to actuate the lever connections, the

plunger is lowered,- closing the passage through theopenings 3Opreventing further.

filling of the tank and compressing the spring Should a be desired to anthe tank in excess of the amount normally required, the

knob l3 may be depressed, causing the opening 3a in the plunger-toregister with the openings 30, and permitting water to fur ther enterinto the tank.

Due to the leverage of theseveraloperative connections it will beevident that the action 01'? the plunger is positiveand rapid, formingan eiiective device for the purpose indicated and which is extremelysensitive to the rise or iallof liquids Within the tank.

Having thus described my invention, what I claim as newand desire tosecure by Letters Patent, is-

1; In a control valve, the combination with a bored cylindrical body,having registering inlet and outlet openings. passing therethrough, aplunger movable in .said body adapted to control the openings, springactuated means for normally holding; said plunger in a raised position,a tank to receivethe flow'from said outlet, a vertically movablespindle, a float in said tank en- I gaged with the lower end of saidspindle, an arm attached to said spindle, a lever engage'dtherewith, asecond lever engaged on the support for said spindle, a head on saidplunger in which the second lever engages,
